BOOT-CRIMPING IVIACHINE.

Specification of Letters Patent No. 27,561, dated March 20, 1880.

To all whom it may concern:

Be it known that we, JOHN S. NOLEN and C. C. HINCHMAN, both ofPaulsboro, in the county of Gloucester and State of New Jer sey, haveinvented a new and Improved Boot-Crimping Machine; and we do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, forming apart of this specification, in which Figure 1 represents a frontelevation of the machine, showing the former in an elevated positionwith the follower in dotted lines between one of the jaws of thefollower. This figure also shows the clamp on the former, for stretchingand holding the leather in place on said follower after the clampingoperation. Fig. 2 is a vertical transverse section of Fig. 1, showingthe parts in the same relative positions.

Similar letters of reference indicate corresponding parts in bothfigures.

The nature of this invention consists in giving elasticity to thefollower, which is interposed between two jaws for the purpose offacilitating the removal of the finished boot front, and so that it willadapt itself to the convex surface of the former, when said former isforcibly brought down upon it, with the latter attached thereto, therebypreventing any uneven strain on the leather, and so that the work willbe smoothly crimped when removed from the press; as will be hereinafterdescribed.

To enable those skilled in the art to fully understand our invention, wewill proceed to describe its construction and operation.

In the drawings, A, A, A, A, represent respectively, the foundation,uprights, and cross brace, of the frame of my boot crimping machine.These parts are made strong and substantial, of either metal or wood.

In the base portion A, is a fixed jaw, B, shown clearly by Fig. 2 of thedrawings, with a base strip 0, interposed between it, and a movable jawD, similar in shape and size to jaw B. The inside surface of both jawsare parallel with each other.

E is a shaft furnished with a handle E, which passes through both jawsB, D, and is tapped in a nut a, in jaw B, and has a collar Z) fixed toit on the outside of jaw D, with this shaft the movable jaw may be madeto approach or recede from the fixed jaw B Between these two jaws B, D,the follower G, the top edge of which grooved as shown, and conforms tothe lower male edge of the former H, both of which edges are formed inaccordance with the desired shape to be given to the boot front whenfinished. This follower G, is mounted on springs J, J, which rest onstrip C. These springs wien relieved, elevate the follower, between thejaws B, D, sutficiently to allow the former H, with the boot frontattached to it, to be readily removed from the machine, or from the jawsB, D, and when the former H, is forcibly brought down with the leatheron it, the follower receives it at the point shown by the drawings, andgradually adapts itself to the edge of the former, as the pressure isincreased, then when the follower reaches the strip C, the leather is ina fit state to receive the final crimping pressure, the leather is thenpressed on the sides by setting up the jaw D. The power required by thisoperation is exerted by means of a lever K, which is pivoted to oneupright of the frame, and at its fulcrum it is connected to a forked rodM, having its guide in the cross bar A, of the frame; the lower ends ofthe forked arm, rest on the former H, which is held in its proper placein the frame by guide strips 6, e, nailed to each upright, all asclearly shown in the drawings.

After the boot front has been properly crimped, or stretched, as abovedescribed, and before it is removed from its confined state, between thejaws B, D. it is tacked to the former and further confined to it by aclamp to be hereinafter described; when this is done, the jaw D isrelieved, when the former will be forced up by the springs under thefollower. The former, with the leather attached to it as abovedescribed, is then removed from the machine to dry, and another formerintroduced for a similar operation.

The shaft E, above referred to, passes through a vertical slot in thefollower as shown by Fig. 2, so as to allow the follower a free verticalplay, between the aws.

The device for clamping the boot front to the former, consists of twobent plates N, N, with a set screw P, passing through their heads asshown in Fig. 2. The inside sur face of N, and the outside surface of N,are

serrated, and between these two jaws the edge of the leather is placed,when the clamp is astride the top of the former; then by turning thescrew 1?, the jaws will firmly 5 grip the leather at the same time drawthe leather tight on the former.

The advantage of this device is that it is adjustable to a variety ofsizes of leather fronts, and that the leather is griped, and 10 drawnsimultaneously.

Having thus described our invention,

What we claim and desire to secure by Let ters Patent, is,

The follower, Gr, springs J, J, with adjustable jaws B, D, and former H,when the same are arranged and combined essentially as, and for thepurpose set forth.
